Update README.md

I was having a relaxing night, so I decided to offer a few copywriting tweaks to tighten wording and correct typos. I hope it helps! One thing: It’s unclear to me whether “Uses openssl with the aes-256-cbc ciper” *[sic]* is a *STEP* in the encryption process or just a *NOTE* about secure data transmission. If it’s the *former* you might explain *WHAT* it does. If it’s the latter, you might consider moving it to the end of the section by itself as a final section note.

### Password generation
Passman features a build in password generator.
Not it only generates passwords, but it also measures their strength using [zxcvbn](https://github.com/dropbox/zxcvbn).
Passman can generate passwords *and* measure their strength using [zxcvbn](https://github.com/dropbox/zxcvbn).

Generate passwords as you like
![](http://i.imgur.com/jcRicOV.png)
Passwords are generated using the random functions from `sjcl`.
Passwords are generated using `sjcl` randomization.
### Storing credentials
All passwords are encrypted client side using [sjcl](https://github.com/bitwiseshiftleft/sjcl) which uses AES-256 bit.
Users supply a vault key which is feed into sjcl as encryption key.
After the credentials are encrypted they are send to the server, there they will be encrypted again.
This time using the following routine:
- A key is generated using `passwordsalt` and `secret` from config.php *so back those up*
- Then the key is [stretched](http://en.wikipedia.org/wiki/Key_stretching) using [Password-Based Key Derivation Function 2](http://en.wikipedia.org/wiki/PBKDF2) (PBKDF2).
- [Encrypt-then-MAC](http://en.wikipedia.org/wiki/Authenticated_encryption#Approaches_to_Authenticated_Encryption) (EtM) is used for ensuring the authenticity of the encrypted data.
- Uses openssl with the `aes-256-cbc` ciper.
- [Initialization vector](http://en.wikipedia.org/wiki/Initialization_vector) (IV) is hidden
- [Double Hash-based Message Authentication Code](http://en.wikipedia.org/wiki/Hash-based_message_authentication_code) (HMAC) is applied for verification of the source data.
All passwords are encrypted client side with [sjcl](https://github.com/bitwiseshiftleft/sjcl) using 256-bit AES.
You supply a vault key which sjcl uses to encrypt your credentials. Your encrypted credentials are then sent to the server and encrypted yet again using the following routine:

## Docker
To run Passman with [Docker](https://www.docker.com/) you can use our test docker image.
You have to supply your own SSL certs, self signed or Let's encrypt it doesn't matter.
Please note that the docker is only for testing purposes, as database user / password are hardcoded.
To run Passman with [Docker](https://www.docker.com/), use our test Docker image. Supply your own self-signed SSL certs or use [Lets Encrypt](https://letsencrypt.org/). Please note: The Docker image is for _testing *only*_ as database user / password are hardcoded.
If you like to spiece up our docker image and make it a full fledged secure, production ready install, you're welcome to do so.
Please note that:
If youd like to *spice up* our Passman Docker image into a full-fledged, production-ready install, youre welcome to do so. Please note:
- Port 80 and 443 are used
- SSL is enabled (or disabled if certs not found)
- Startup time of container must be less than 15 seconds
- SSL is enabled (or disabled if no certs are found)
- Container startup time must be less than 15 seconds
Example:
```
docker run -p 8080:80 -p 8443:443 -v /directory/cert.pem:/data/ssl/cert.pem -v /directory/cert.key:/data/ssl/cert.key brantje/passman
```
If you want a production ready container you can use the [Nextcloud docker](https://hub.docker.com/_/nextcloud/), and install passman as an app.

## Development
Passman uses a single `.js` file for the templates. This gives the benefit that we don't need to request every template with XHR.
For CSS we use SASS so you need ruby and sass installed.
`templates.js` and the CSS are built with `grunt`.
To watch for changes use `grunt watch`
To run the unit tests install phpunit globally, and setup the environment variables on the `launch_phpunit.sh` script then just run that script, any arguments passed to this script will be forwarded to phpunit.
